Nutritional guidelines emphasize fish consumption due to its reported health benefits, although the potential differential effects based on the cooking method used have not been well investigated. Hypothesizing that fish consumption and preparation method may affect lipid concentrations, we aimed to examine fish consumption per dietary guidelines adherence and assess the association between fish intake and dyslipidemia likelihood in Greek adults. Fish consumers were identified using 24-hour recalls and a validated Food Propensity Questionnaire from 3742 adults (aged ≥19 years, 59.3% females). Dyslipidemia likelihood was estimated using adjusted logistic regression models, for total intake, and for nonfried and fried-fish consumers. Prevalence of fish consumers was 17.9% (n = 668), and 20.8% (n = 139) reported frying it. Based on the Food Propensity Questionnaire, and in combination with the two 24-hour recalls, 67.7% of fish consumers and 66.9% of fried-fish consumers consumed it less than once per month, resulting in a median weekly intake of 23.7 (13.7, 56.7) g and 26.2 (15.0, 70.4) g, respectively. For each gram of total fish intake, the odds of dyslipidemia decreased by 3% but consuming fried fish 1 to 3 times /month compared to <1 per month, increased the odds by 3.6% (odds ratio, 3.6; 95% confidence interval, 1.19–10.70). Greek adults do not adhere to the dietary guidelines for fish consumption in terms of weekly intake and a large proportion consume it fried. Both factors may lead to a further increased likelihood of dyslipidemia and not to a protective effect. Public health educational awareness programs are required to increase the frequency of fish consumption, with emphasis given on cooking methods.

营养指南强调食用鱼类，因为据报道它对健康有益，尽管基于所使用的烹饪方法的潜在差异影响尚未得到充分调查。假设鱼的摄入量和制备方法可能会影响脂质浓度，我们的目的是检查希腊成年人遵守膳食指南的鱼摄入量，并评估鱼摄入量与血脂异常可能性之间的关系。通过24小时召回和经过验证的食物倾向问卷，对3742名成年人（年龄≥19岁，59.3%为女性）的鱼类消费者进行了识别。使用调整后的logistic回归模型，对总摄入量、非油炸和油炸鱼的消费者进行血脂异常可能性的估计。鱼类消费者患病率为17.9% (n = 668), 20.8% （n = 139）报告油炸。根据食物倾向问卷，并结合两次24小时召回，67.7%的鱼类消费者和66.9%的炸鱼消费者每月食用不到一次，导致每周摄入量的中位数分别为23.7 (13.7,56.7)g和26.2 (15.0,70.4)g。每摄入1克鱼，血脂异常的几率会降低3%但每月食用1至3次炸鱼与

Skin carotenoids can be measured non-invasively using spectroscopy methods to provide a biomarker of total dietary carotenoid and carotenoid-rich fruit and vegetable intake. However, the degree to which skin carotenoid biomarkers reflect intakes of specific carotenoids must be determined for specific devices. Previously, findings were mixed regarding the correlation between reflection spectroscopy (RS)-assessed skin carotenoids and individual plasma carotenoid concentrations. The current study expands on prior analyses to examine the cross-sectional associations between adult RS-assessed skin carotenoids and individual carotenoid species intakes and plasma concentrations, controlling for potential covariates. We hypothesized that RS-assessed skin carotenoid scores would strongly correlate with all major plasma carotenoid species other than lycopene. Cross-sectional data from 2 prior studies (n = 213 and n = 162) examining the validity and sensitivity of RS-assessed skin carotenoids as a biomarker of fruit and vegetable intake were used. Skin carotenoids were assessed using the Veggie Meter, which quantifies combined skin carotenoid concentrations. Plasma concentrations of α-carotene, β-carotene, β-cryptoxanthin, lycopene, and lutein and zeaxanthin were determined using high-performance liquid chromatography. Self-reported carotenoid intake was estimated from validated food frequency questionnaires. Skin carotenoid scores correlated moderately to strongly with individual plasma carotenoid species (Pearson's r = 0.52 to r = 0.78) except for lycopene (r = 0.04 to r = 0.07). Low correlations between skin carotenoid score and lycopene plasma concentrations and intake could be due to differential deposition, preferential oxidation/degradation, and/or device measurement bias. Validating skin carotenoid measurement techniques relative to other concentration biomarkers informs the interpretation of skin carotenoid biomarkers.

皮肤类胡萝卜素可以使用光谱学方法无创测量，以提供总膳食类胡萝卜素和富含类胡萝卜素的水果和蔬菜摄入量的生物标志物。然而，皮肤类胡萝卜素生物标志物反映特定类胡萝卜素摄入量的程度必须针对特定设备确定。以前，关于反射光谱（RS）评估的皮肤类胡萝卜素和个体血浆类胡萝卜素浓度之间的相关性，研究结果是混合的。目前的研究扩展了先前的分析，以检查成人rs评估的皮肤类胡萝卜素和个体类胡萝卜素的摄入量和血浆浓度之间的横断面关联，控制潜在的协变量。我们假设rs评估的皮肤类胡萝卜素评分与除番茄红素外的所有主要血浆类胡萝卜素种类密切相关。本研究使用了先前两项研究（n = 213和n = 162）的横断面数据，以检验rs评估的皮肤类胡萝卜素作为水果和蔬菜摄入量生物标志物的有效性和敏感性。皮肤类胡萝卜素的评估使用蔬菜计，量化综合皮肤类胡萝卜素的浓度。采用高效液相色谱法测定血浆中α-胡萝卜素、β-胡萝卜素、β-隐黄质、番茄红素、叶黄素和玉米黄质的浓度。自我报告的类胡萝卜素摄入量是通过有效的食物频率问卷来估计的。除了番茄红素（r = 0.04 ~ r = 0.07）外，皮肤类胡萝卜素评分与血浆类胡萝卜素的种类有中等到强烈的相关性（Pearson’s r = 0.52 ~ r = 0.78）。皮肤类胡萝卜素评分与番茄红素血浆浓度和摄入量之间的低相关性可能是由于不同的沉积、优先氧化/降解和/或设备测量偏差。验证皮肤类胡萝卜素相对于其他浓度生物标志物的测量技术有助于解释皮肤类胡萝卜素生物标志物。

Young adulthood is an influential life stage for developing lifelong eating patterns, yet limited research characterizes dietary intake among young adults. This cross-sectional study assessed dietary intake and characteristics associated with nutrition knowledge and healthy food consumption among college students. We hypothesized that healthy food intake would be lower than United States (U.S.) dietary guidelines and that perceived healthy eating barriers would be negatively associated with diet quality. Participants were undergraduate college students enrolled in an introductory human nutrition course (N = 762), with surveys administered during the first week of class. Survey instruments included the Dietary Screener Questionnaire developed by the National Cancer Institute and the Jones Nutrition Knowledge questionnaire. Perceived encouragement, cost, taste, and ease of eating healthier foods were assessed with questions from the National Health Interview Survey. College student daily mean intakes of fiber (15.46 ± 3.06 grams), whole grains (0.63 ± 0.29 ounce equivalents), combined fruits and vegetables (2.38 ± 0.73 cup equivalents), and dairy (1.49 ± 0.53 cup equivalents) were lower than U.S. recommended dietary guidelines, while mean intakes of added sugars (14.65 ± 4.01 teaspoon equivalents) were greater than recommendations. As hypothesized, dietary intakes of young adult college students were sub-optimal, not meeting the U.S. dietary guidelines for fiber, whole grains, fruits, vegetables, dairy, and added sugars. Additionally, perceived ease of eating healthier foods, cost, and nutrition knowledge were significantly associated with increased consumption of healthier foods. Results highlight the need to reduce barriers to improve healthy eating among young adults.

Hyperlipidemia, hepatic steatosis, and hyperglycemia are prevalent metabolic disorders closely linked to obesity. The objective of this research was to examine the potential advantageous impacts of polyphenols extracted from Prunus salicina L. fruit (PSFP) on hyperlipidemia, hepatic steatosis, and hyperglycemia induced by a high-fat diet (HFD), as well as to elucidate the underlying mechanisms involved. Male C57BL/6J mice, free from specific pathogens, were assigned randomly into three groups. These groups were then subjected to a 14-week dietary intervention, including a low-fat diet, an HFD, or an HFD plus with PSFP via intragastric administration. The obesity-related biochemical indexes were evaluated. To assess alterations in gut microbiota resulting from PSFP treatment, 16S rRNA sequencing was performed. UPLC-ESI-MS/MS assay identified 162 distinct polyphenolic compounds in PSFP. The administration of PSFP significantly reduced both body weight gain and hyperlipidemia induced by HFD. In addition, PSFP ameliorated hepatic steatosis induced by HFD and enhanced liver function in mice. PSFP treatment also ameliorated HFD-induced insulin resistance and hyperglycemia, evidenced by the observed decrease in fasting serum concentrations of glucose and insulin, improved insulin sensitivity, and restored glucose tolerance. Moreover, PSFP modulated the composition and abundance of specific microbial genus, including Lachnospiraceae NK4A136 group, Akkermansia, Parabacteroides, Enterococcus, Adlercreutzia, and Roseburia. Correlation analysis indicated significant associations between gut microbiota and physiological indices associated with obesity. These findings suggested that PSFP supplementation ameliorated HFD-induced hyperlipidemia, hepatic steatosis, and hyperglycemia, potentially through modulating the gut microbiota composition and abundance of specific taxa.

高脂血症、肝脂肪变性和高血糖是与肥胖密切相关的常见代谢疾病。本研究的目的是探讨从水杨梅果实（PSFP）中提取的多酚对高脂饮食（HFD）诱发的高脂血症、肝脂肪变性和高血糖的潜在有利影响，并阐明其中的潜在机制。雄性 C57BL/6J 小鼠在没有特定病原体的情况下被随机分为三组。然后对这些组进行为期 14 周的饮食干预，包括低脂饮食、高脂饮食或高脂饮食加胃内给药 PSFP。对肥胖相关的生化指标进行了评估。为了评估PSFP治疗导致的肠道微生物群变化，进行了16S rRNA测序。UPLC-ESI-MS/MS分析鉴定了PSFP中162种不同的多酚化合物。服用 PSFP 后，高氟日粮引起的体重增加和高脂血症均明显减少。此外，PSFP 还能改善高脂饮食引起的肝脏脂肪变性，增强小鼠的肝功能。PSFP 治疗还能改善高纤维食物诱导的胰岛素抵抗和高血糖，这体现在观察到的空腹血清葡萄糖和胰岛素浓度的下降、胰岛素敏感性的改善以及葡萄糖耐量的恢复。此外，PSFP 还调节了特定微生物属的组成和丰度，包括 Lachnospiraceae NK4A136 组、Akkermansia、Parabacteroides、Enterococcus、Adlercreutzia 和 Roseburia。相关性分析表明，肠道微生物群与肥胖相关的生理指标之间存在明显的关联。这些研究结果表明，补充 PSFP 可改善 HFD 引起的高脂血症、肝脂肪变性和高血糖，这可能是通过调节肠道微生物群的组成和特定类群的丰度实现的。

The objective was to determine if whole milk intake or total milk intake behaviors are associated with body weight (weight) and related parameters in adults. We hypothesize that whole milk intake would be inversely associated with body weight measures. Whole milk (including flavored whole milk) intake was assessed using 24-hour dietary recall data of the National Health and Nutrition Examination Survey 2001-2018 for adults age 20+ years (N = 43,038). Weight and related parameters were measured, and history of self-reported weights and total milk intake were obtained from questionnaire data. The association of whole milk intake with weight was assessed via regression after adjusting for demographic and lifestyle-related covariates. The average body mass index (BMI) was about 29 kg/m² and weight was 76 to 89 kg. About 66% of the population were overweight or obese. Average whole milk intake among consumers was 1.0 to 1.4 cups eq/d. Whole milk intake was inversely associated (P < .05) with weight, BMI, waist circumference, and the prevalence of obesity. Whole milk intake was also inversely associated (P < .01) with trying to lose weight in the past year. In most cases, milk intake behavior at ages 5 to 12, 13 to 17, or 18 to 35 years was not associated with BMI. The results indicate that whole milk intake was inversely associated with weight, BMI, and prevalence of obesity, and these findings may provide additional evidence to support dietary recommendations for whole milk.

目的是确定全脂牛奶摄入量或牛奶总摄入量行为是否与成年人的体重（重量）及相关参数有关。我们假设全脂牛奶的摄入量与体重测量值成反比。全脂牛奶（包括调味全脂牛奶）的摄入量是通过 2001-2018 年全国健康与营养调查中 20 岁以上成年人（N=43,038）的 24 小时膳食回忆数据进行评估的。对体重和相关参数进行了测量，并从问卷数据中获得了自我报告体重和牛奶总摄入量的历史记录。在对人口统计学和生活方式相关协变量进行调整后，通过回归评估了全脂牛奶摄入量与体重的关系。平均体重指数（BMI）约为 29 kg/m2，体重为 76 至 89 kg。约 66% 的人口超重或肥胖。消费者的全脂牛奶平均摄入量为 1.0 至 1.4 杯当量/天。全脂牛奶的摄入量与体重、体重指数、腰围和肥胖率成反比（P < .05）。全脂牛奶的摄入量还与过去一年中尝试减肥的次数成反比（P < .01）。在大多数情况下，5 至 12 岁、13 至 17 岁或 18 至 35 岁的牛奶摄入行为与体重指数无关。结果表明，全脂牛奶的摄入量与体重、体重指数和肥胖症的发生率成反比，这些发现可能为支持全脂牛奶的膳食建议提供了更多证据。
